In the figure below, given a
triangle ABC, BD is the median to AC, angle BCA = a
, and angle ABD = 90º -
a. Prove that
x = a.

FACTS AND HINTS:
Geometry problem solving is one of the most challenging skills for students to learn. When a
problem requires auxiliary construction, the difficulty of the problem increases drastically, perhaps because deciding which construction to make is an ill-structured problem. By “construction,” we mean adding geometric figures (points, lines, planes) to a problem figure that wasn’t mentioned as "given."
